Bob Tisdale just wrote a paper showing that the so-called sea level rise "hotspots" on the Atlantic and Pacific coasts are not "accelerating" at all, that the trend has been falling since 2002 rather than rising, and that the sea-level anomalies appear to be correlated with the 30-year ENSO cycle.
As with global warming, if you have an agenda you can start and end your short-term plot wherever you see fit to make your point and cause some excitement. But if you are an ethical scientist, and look at how to arrive at all the different trends and their merits like Bob has done here, you get a much less exciting result.
